Answer:
slope = -1
Step-by-step explanation:
parallel lines have the same slope,
y = -x – 4
=> y = -1(x) -4
↑ slope
y = mx + b
↑ slope
F = kry
f/kr = y
y = f/kr
Answer: y = f/kr

The answer is D, x=12. There's a lot of little math involved but hope it helps!!
Answer:

Step-by-step explanation:
-This is an LCM problem.
-To simplify, we introduce a least common multiplier which is equivalent the product of the denominators:

#We introduce the LCM and adjust the fractions based on it :

Hence, the simplified form of the fraction is: 
It shouldn't be too hard, I've been taking my practice test all day today and yesterday night and I believe i'm going to do good today on my test, just study hard and take the practice test
